As the green flag waves for the start of the Hollywood Casino 400 at Kentucky Speedway on Sunday, seven drivers will face what the Merriam-Webster dictionary describes as "the stress or urgency of matters demanding attention." In other words, pressure.There is so much on the line as the Cup Series Playoffs wind down that even the smallest mistake could end someone's dream of taking home the Bill France Trophy next month.One spot in the Championship Four is off the board, courtesy of NASCAR’s series-best ratings leader Kyle Larson. But the remainder of the Round of 8 hopefuls is one of the most balanced fields in recent memory, combining for 15 victories and a whopping 37 stage wins.What to watch for at the Hollywood Casino 400Entering the 2021 Hollywood Casino 400, Ryan Blaney (+17), Denny Hamlin (+9), and Kyle Busch (+8) are holding serve above the cut line, but their leads are precarious at best. Joey Logano is the furthest back in eighth down by 43, courtesy of a disastrous DNF a week ago.A checkered flag would vault Logano into second place and erase any doubts about his qualifications as a title contender. But Vegas Insiders isn't as bullish on his chances as he is -1600, its ninth choice despite having the most Playoff wins of any driver at this track with three (2014, 2019, 2020).Meanwhile, defending 2020 Cup Series champion Chase Elliott, eight points behind Kyle Busch and just below the final transfer spot, won’t go away quietly. Brad Keselowski (-15) and Martin Truex Jr. (-22) are both former titleholders, winning in 2012 and 2017 respectively, and are not going to roll over and play dead just because of where they are in the standings.Statistically, the Super Seven have an aggregate of 10 victories at Kansas Speedway, with only Blaney failing to take a checkered flag, so they know their way around the mile-and-a-half asphalt track.NASCAR@NASCARHe was the man to beat in Texas, now he'll be the first driver to see the green in Kansas.@KyleLarsonRacin wins the #BuschPole for @kansasspeedway!9:00 AM · Oct 20, 20211017115He was the man to beat in Texas, now he'll be the first driver to see the green in Kansas.@KyleLarsonRacin wins the #BuschPole for @kansasspeedway! https://t.co/nkGbU5YwjaCan anyone stop Kyle Larson at the Hollywood Casino 400?Kyle Larson has locked himself onto the Championship Four following his victory at Texas Motor Speedway last weekend.
